ROLLER CARRIAGE.

Application filed May 11, 1923. Serial No. 638,349.

To all `'io/0m it may conce/m.'

Be it lrnown 'that l, tir-Lonen lfannirnriv MA'rrEsoN, a citizen oi' the United States, residing at Rocky Hill, in the county or Hartford and State or Connecticut, have invented certain new and user'ul improvements in Roller Uarriages, oi which the 'toliowing is a speeil'ication. j

My said invention relates to a roller trip mechanism for printing presses and it is an object or the same to provide a device or the character described with improved latch-v ing means Iror holding one or more inliing rollers out ot 'ioi'ni-e1i.gagi1ig position, said iatching means being positively operated to release the form rollers for contact with the ink cylinder and being also positively released at the lower end of their travel `by means traveling at substantially theV saine speed as the roller carriage, thus doing away with f the destructive action occurring in certain known types ot trip mechanism due to the shock caused by the striking o'r a latch or connected part on the roller carriage against a rigid abutment on the lined iframe or the press. As in `lnown mechanisms of this type freshly inked rollers are applied to the bottom of the rorm on the upward strolre or' the roller carriage thus eli'ecting a double rolling or the torni at each revolution or' the press but the latch operating devices travel with the roller carriage and substantially at the same speed as the latch or latches. l

Another object of the invention is to provide a simple and eii'ective operating means i'or releasing a plurality ot latches where it is desirable to hold out a plurality olf torni rollers at some stage of the operation.

Another object or the invention is to provide a latch ot' improved shape for cooperat ing with an abutment on the ournal box ot a form roller for holding it away from the rorm.

Still another kobject of the invention is to provide improved means toinsure the release or' the form rollers from their outermost inoperative position before-they reach a position ot interference with the form grippers and platen.

Referring .to the accompanying drawings", which are made a part hereof and on which .similar reference characters indicate similar.

parts,

Figure 1 is an elevation orl part otra printing press with my improved device attac-hed ot form rollers indicated at 16 and 1"?. The

form rollers are rotatably. mounted in journai bearings 1S and these journal bearings have laterally projecting stems 19 slidably mounted in horizontal openings in aside member 2O of the carriage.v Springs 21 sur round the ste-ms 19 and bear at one ond against aff-lange of the member 2O and at the other'end against abutments 22 on the stems, which abutments are here indicated as consisting of washers held in place by cotter pins 23.`

A pair oi screws 24C project laterally from the .sideof the rollerr carriage and a bar 25 is held in place by the screws, slots being provided at 26 in said bar to permitthe sameto move relatively to the carriage. Each of the journal bearings for the form rollers isv provided with an inclined cam tace at 27 and the bar has correspondingly inclined surfaces at 28 whereby when the bar is moved downward relatively to the carriage the opposed inclined faces oi'l each pair will slide over another and force the sov journal bearings with'the form rollers to the lble lever 29 pivoted at 3() and having a ball at Siena-aging a socket` in the sliding har.

' A rockarm 32 on a rockshaft indicated at 33 in dotted lines is provided as usual for moving the rollercarriage up and. down, it being connected thereto by a link 33 pivoted to the carriage at 34 which also functions as a lever to release the latches on the carriage. `A nose 35 on the lever, is adapted to engage an abutment at the lower right hand corner of a latch 36 in the form of a pawl pivotally mounted on the roller. carriage and notched at its 'forward end to provide a vertical face adaptedv to engage with a projecting abutment 37 in the form of a pi'n onthelower1nost journal boX. A lateral arm 38 on the lever 33 is bent upward at its outer end and adapted to strike the lowerend of the slide 25 and: push the slide up to disengage it from the journal boxes before the roller carriage has traveled far enough to strike against the frame grippers or the platen of the press, the springs 21 then acting to return the rollers 17 to forinengaging position and the rollers 16 to the intermediate position where they are temporarily held by the latches herein described.

In some cases' it is desirable to provide more than one of the form rollers with means for holding it away from the face offthe type on the downward stroke of the carriage and for this purpose I have'pro- 'videdan additional latch 39v also pivotally mounted on the carriage and generally similartov the latch 36 but provided with a downward projection 40 in place oflthe operating means for the latch 36. It will be evident that when the latch 36 is raised, the latch V39 will also be raised out of engagement with its pin 37.

In the operation of my device it Will. be seen that when the roller carriage is in its uppermost position as shown, the hand lever 29may be operated to move the slidingbar 25 downward and so force the form rollers into their outer inoperative position where they will be held until the bar is moved upward to release them. This may ordinarily be done by the operative before starting the press but should he forget or neglect to do so then as the link 33 draws the carriage down the upper end of arm 38 will swing about the pivot 34 so as to raisey the.l slide and release the rollers to the action of the springs before reaching a position to causev damage.

As the carriage approaches its lowerinost position the. wheels ofthe lower paillv of rollers 16 will ride up over cams`13 and 14 respetlively. but out of contact with the cams 'since the rollers are held in their outer position by latches 36 and'39; Rockarm 32 is now at its lowermost position. the link and carriage 25 having been moved down by it intov a .position where Athe link 33 stands at substantially the same angle to the carriage as' in the uppermost position of said part-s. In this position thenose 35 strikes against the latch 36 and lifts it out of engagement with the projection 37, this latch in turn lifting the upper latch 39 by means of its lug 40. Then the latches are thus lifted out of the position indicated. in Figure 2 the springs 21 move theL journal bearii'igs and therefore the4 lower pair of forni rollers toward the right. If the cams .13 and 1 4 were absent the wheels of the form rollers would strike noisily on their tracks, but: with theiconstruction shown they impinge first on the high points of the cams, already close to the wheels and then ride gently down the camfacesto the tracks7 when the freshly inked rollers apply the ink beginning at the lower end of the form as specified. As the carriage approches its upper positionthe wheels-olf lthe form rollers ridel over the cam 15 andforce the journal bearings of the lower pair ofl rollersfto, the left-into a positionA where they would be engaged by the latches butv for the fact thatr the link 33 by means of its nose 35 lifts the latches into the positionindicated in Figure 1 so that all thel rollers are in-position to. engage with the ink cylinders 41 and 42' respectively as the carriage travels at low speed toward its upper position. Vlhen the carriageagain starts down the truck wheels roll over the cam 15 andas the nose 35 is now at or near the position of Figure 2 the latches again engage behind the pins 37 thereby holding the lower pair of form rollers out ofA form-engaging position so that the upper part of the form isinked bythe upper pair of rollers while the lower pair of yrollers is `adapted to act withfull'e'iect onthe. lower end of the forniduringA the reverse stroke of the carriage in a manner. well understood inthe art.

It will beobvious to those-skilled in the art that. the details of my invention. may bel modified in various waysy without departingfmm the spirit of the invention, and therefore I do not limit myself to the specific embodiment shown in the drawings and described in the specification but only as indicated in the appended claims.
